Fibrous Dysplasia Involving Mandible and Maxilla: A Case Report

Abstract

Fibrous dysplasia (FD) is a benign fibro-osseous lesion in which normal bone is replaced by fibrous connective tissue and irregular trabeculae of immature bone. This report presents a case of an 18-year-old male with an extensive hard bony swelling involving the left mandibular and maxillary regions, resulting in marked facial asymmetry. The swelling extended from the parasymphysis region of the mandible to the neck of the condyle posteriorly and superiorly involved the maxillary zygomatic region. Surgical management was performed using an extraoral approach for the mandible and an intraoral vestibular approach for the maxilla, with bone contouring and saucerization. Post-operative healing was uneventful, and the patient showed significant improvement in facial symmetry. This case highlights the importance of early diagnosis and conservative surgical management in craniofacial FD to achieve favorable esthetic and functional outcomes.
